HARROW.

SPECIFICATION forming part of Letters Patent No. 397,605, dated February 12, 1889. Application filed J 11119 2 1883. Serial No. 275,809. (No model.)

To all whom it may concern:

Be it known that I, HUGH A. MURPHY, a citizen of the United States, residing at Elk City, in the county of Montgomery and State of Kansas, have invented a new and useful Improvement in Harrows, of which the follow ing is a specification.

My invention relates to an improvement in harrows for listed crops; and it consists in the peculiar construction and combination of devices that will be more fully set forth hereinafter, and particularly pointed out in the claims.

This invention is an improvement in the harrow for which Letters Patent of the United States No. 378,611 were granted to me February 28, 1888.

In the accompanying drawings, Figure 1 is a top plan view of aharrow embodying my improvement. Fig. 2 is a side elevation of the same. Fig. 3 is a front elevation of one section of my improved barrow. Fig. 4 is a vertical transverse sectional view of the same taken on the line :10 0c of Fig. 1. Fig. 5 is a rear elevation. Figs. 6 and 7 are detail views.

A represents a series of three or more harrow-sections arranged side by side and each of which constructed follows: B represents a pair of rearward-diverging beams, which may be made of wood, but which are preferably made of gas or water pipes. To these beams are secured harrow or cultivating teeth 0, of suitable construct-ion.

D represents an inverted U-shaped yoke of suitable width, which is provided with vertical depending arms E.

F represents a pair of right-angled coupling-irons, which are provided in their lower horizontal arms with a series of openings, G, and have their vertical arms secured to the arms E of the yoke by means of bolts H. The horizontal arms of the right-angled coupling-irons extend inward toward each other, as shown, and the front ends of the harrowbeams B are pivotally connected thereto by means of bolts I, which extend through the front end of the said beams and are adapted to engage either of the openings G. By this means it will be understood that the front ends of the beams may be secured at any desired distance apart, so as to enable plants to pass through the space between the front ends of the beams when the harrow is drawn forward in operation.

K represents an inverted U-shaped yoke, which is similar to the yoke D, but is much wider than the latter; and L represents a pair of right-angled coupling irons, which are similar to the coupling-irons F, and are bolted to the vertical arms of the yoke K on the outer sides thereof, the horizontal arms of the said right-angled coupling-irons L extending outward in opposite directions and being provided with vertical adj ustingopenings M for the reception of bolts N, which are employed to secure the harrow-beams near their rear ends to the said couplingirons. By reason of a series of openings, M, the harrowbeams may be adjusted laterally at their rear ends toward and from each other, according to the width of the rows.

0 represents a pair of crossed diagonal. brace bars, which have their ends bolted to the yokes D K, at the corners of the latter, and thereby serving to rigidly connect the said yokes, as will be readily understood.

On the outer side of each barrow-beam B, at the rear end thereof, is bolted a curved standard, P, and to the lower end of said curved standard is pivoted the upper end of So a cultivatingplow, R. The lower ends of the said standards are bifurcated to receive the upper ends of the cultivating-plows, and the said stan dards are also provided with openings S to receive frangible pins T, the function of the said pins being to normally secure the plows to the standard at the correct inclination, and to break when the plows encounter inflexible obstructions, so as to enable the cultivating plows or shovels to incline rearward on their pivotal bolts, and thereby clear the obstruction without being injured thereby.

U represents a pair of side wings, which are provided each with a series of harrows or cultivating-teeth, and are similar in 5 construction to the beams B, with the GXCGP' tion that they are shorter than said beams. The said beams U or side wings are arranged on the outer sides of and parallel with the beams B, and are connected near their rear IOO ends to the vertical arms of the rear yoke, K,

by means of arms V, which have their inner ends pivoted or hinged to the said arms of the yokes, and their outer ends secured to the siderable elevation from the barrow-beams 13, Y

and consequently the said side wings or beams are adapted to ride on the opposing sides of the ridges and cultivate and stir the same, while the teeth or cultivators attached to the beams 13 are stirring the soil in the furrows between the ridges and on opposite sides of I 1 their upper ends secured to the upper ends the rows of growii'lg plants.

Y represents a pair of rods which have 5 their ends secured to the lower ends of the vertical arms of the rear yoke, K, and. to the upper side of the front yoke, 1).

Z represents a draltt-chain, which has its ends attached to the front ends of the yoke D.

A represents an evening-bar which is arranged transversely in front of the series of harrowsections, and is connected to the chains Z. To the ends of the said evener are secured brackets B, having spindles C, on which are journaled supporting-wheels D of suitable diameters, and adapted to cause the evenor to be supported at such an elevation from the ground that the evener will pass over the growing plants without coming in contact with them and injuring the same. If preferred, runners may be substituted for the said supporting-wheels.

a represents vertical standards, which have their lower ends pivoted between ears i), which are on the centers of the rear yokcs, K. The pivotal bolts which connect the lower ends of the standards to the rear yokes are arranged in line with the major axes of the harrow-section, so that the standards are adapted to swing laterally.

To the upper end 01 the standard,which is attached to the central barrow-section, is secured a block, 0, which is made of two separable sections, 6, bolted together, and between the said sections are formed spherical concavities or sockets f.

g represents brackets, which are attached to the upper end of the outer standards, a, and have inwardly-extending arms 72, which are provided with vertical guideways 1'.

it represents stirrups, which are pivoted to the upper ends of the said outer standards, and are provided each with a transverse opening, I.

m represents a pair of rods, which are provided at their inner ends with balls 11, which are secured in the sockets in the blocks The outer ends of the said rods extend through the slots or guideways i and through the openings Z in the stirrup k, and are secured in the latter by any suitable means. By reason of the guideways i and of the stirrups 71; being pivoted to the outer standard all three of the standards rt are adapted to move laterally in unison.

0 represents boxes or straps, which are arranged on the lower portions of the standards a, and are ada 'ited to move vertically thereon, and are provided with set-screws or clai'npingbolts 1, by means of which they may be secured to the standards at any desired adjustment. From opposite sides of the said boxes; or straps depend arms '1', the lower ends ol which. bear upon the upper sides of the rear yokes, K, and serve to limit the lateral play of the standards.

s represents rods, which have their front ends pivoted in boxes 1 on the centers of the front yokes, D, of the barrow-section and have of the standards a. The function of the said rods is to relieve the standard of lateral strain.

From the foregoing description and by reference to the drawings it will be obvious that. the barrow-sections are adapted to swing loosely on the lower end of -the standards a and to adapt themselves independently of each other to inequalities of the ground.

hen the machine is drawn across the field, the barrow-sections run in the furrows between the sides of the ridges, so as to stir and pulverize the soil on both sides of the rows of growing plants, and the side wings operate on the tops of the ridges and serve to elfectul'llly stir and pulverize the same.

Having thus described my invention, I claim- 1. In a harrow, the combination of the yoke, the right-angled coupling-irons bolted to the vertical arms of the yoke and having the ad justin g-opcnin gs in their horizontal arms, and the beams bolted to and laterally adjustable on horizontal arms of the coupling-irons, substantially as described.

2. The combination of the harrow, and the side beams or wings arranged above the beams of the harrow and adapted to play vertically, substantially as set forth.

3. The combination of the yokes, the harrow-beams secured thereto, the arms and linkrods flexibly secured to the yokes and projecting laterally therefrom, and the side beams or wings secured to the outer ends of said arms and link-rods and supported thereby above the harrow-beams, as set forth.

t. The combination of the harrowsections having the U-shaped connecting-yokes, the side wings or beams, the arms hinged to the rear yoke and projecting outwardly therefrom, the link-rods loosely connected to the front yoke, the side beams or wings being secured to the said link-rods, and secured to and laterally ad j ustable on, the arms, substantially as described.

5. The combination of the harrow-section, the evener-bar attached thereto, the standards a, having their lower ends pivotally secured t0 the barrow-sections, and the jointed rods m, connecting the upper ends of the said standard, substantially as described.

6. The combination, with the harrow-sections, of the standards a, pivotally connected thereto and adapted to vibrate laterally, and the rods 011, having their inner ends connected to the central standard, a, by the ball-andsocket joint, and their outer ends pivotal ly attached to the outer standards, (1, substantially as described.

7. The combination, with the harrmv-sections, of the standards (:1, having their lower ends pivotally attached thereto the verticallyadjustable boxes or straps 0, arranged on the standards and having the arms '1' adapted to engage the upper sides of the harroW-section s, for the purpose set forth, and means, substantially as specified, connecting the upper ends of the standards, substantially as described.

8. The combination, with the harroW-sections, of the standards a, having their lower ends pivotally connected thereto, the brackets g at the upper end of the outer standards, havingthe inwardly-extending arms 71, provided with the Vertical guides i, the stirrup 7e, pivoted to the upper ends 0 of the said outer standard, and the rods on, having their inner ends secured to the upper ends of the central standard by ball-and-soeket joints and their outer ends passed through the guideways 1 and secured to the stirrups 71*, substantially as described.

In testimony that I claim the foregoing as my own I have hereto affixed my signature in presence of two Witnesses.

HUGH A. MURPHY.
